1-2, 3-4 Shift Solenoid Valve Replacement

1-2,3-4 Shift Solenoid Valve Replacement

Removal Procedure





1. Remove the transmission oil pan and filter.

Note:
Do not remove the valve body for the following procedure.

2. Disconnect all the internal wiring harness electrical connectors from the electrical components (1-6).





Note:
Note the orientation upon removal.

3. Remove the 1-2-3-4 shift solenoid retainer.

4. Remove the 1-2-3-4 shift solenoid (2).

Installation Procedure





Caution:
Be sure all solenoids are installed with the electrical connectors facing the non-machined (cast) side of the valve body; otherwise, the solenoids will bind against the transmission case as the valve body bolts are tightened and damage may occur.

1. Install the 1-2-3-4 shift solenoid (2).

2. Install the 1-2-3-4 shift solenoid retainer.





3. Connect all the internal wiring harness electrical connectors to the electrical components (1-6).

4. Install the transmission oil pan and filter.

5. Fill the transmission to the proper level.

Note:
It is recommended that transmission adaptive pressure (TAP) information be reset.

Resetting the TAP values using a scan tool will erase all learned values in all cells. As a result, the engine control module (ECM), powertrain control module (PCM) or transmission control module (TCM) will need to relearn TAP values. Transmission performance may be affected as new TAP values are learned.

6. Reset the TAP values. Refer to Transmission Adaptive Functions (TCM) Transmission Adaptive Functions (TCM).
